Crocell, or Crokel, is the Forty-ninth Spirit, a Great and Strong Duke.
He appears in the form of a form of an angel speaking mystically of hidden
things. He teaches the art of geometry and the liberal sciences, He, at
the command of the Exorcist, will produce great noises like the rushing
of many waters, although there be none. He warms waters and discovers baths.
He was of the Order of Potentates or Powers, before his fall, as he declared
unto King Solomon. He governs 48 Legions
of Spirits.
